Application filed December 10, 1927'. Serial No. 289,229

This invention relates to a heater of the fireplacetype and is designed more particularly as an improvement upon the structure disclosed in my Patent No. 1,649,037 issued to me on November 15, 1927.

One of the objects is to provide a structure of this character adapted to be built into a mantel and chimney and provided with.

readily and supply moisture constantly to the air being heated.

Another object isto provide a heater of the class described which can be utilized for heatmg two or more rooms.

- Another object is to provide a heater which does not detract from the appearance of the 1 room in which it is installed but, on the contrary, constitutes an attractive addition. g

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, withoutdeparting from the spirit of the invention. e

In the accompanying drawin s, ferred form of the invention hasliee In said drawings, Figure 1 is a perspective'view of a mantel in which is arranged the heating apparatus constituting the present invention.

Figure 2 is a horizontal sect-ion, parts being shown in plan. 1

Figure 3 is an enlarged sectlon on line 3-3, Figure 1. Figure 4 isa section on line 4-4, Figure 3. Referring to the figures by characters of reference 1 designates the metal side walls of the casing of the heater, these walls being onnected by a backplate 2 the preshown.

particularly in Figure 3 there being upwardly and backwardly inclined flues 3 above thls plate 2 to provide outlets for products of a 6 between partition 8 and a flue shield 12 which can be made of tal grille if desired. 3

which extends upwardly and is curved forwardly as is shown' combustion. These flues are connected at their front ends as shown at 4 so that 'p ucts of combustion rising above the plate 2 cannot pass between the flues but can only escape through the flues; Connecting the side plates v1 with the plate 2 to form upwardly and forwardly curved fresh air flues 6 and 7 respectively; .The flue 6 is extended rearwardly away from the lower ortion of thepartition plate 8 while flue is extended rearwardly above the lower portion of flue plate 9.

A' top plate 10 is'inclined downwardly and forwardly from the tops of the'flues 3 and constitutes means for deflecting the products of combustion into said'flues; This top plate or deflector 10 constitutes the bottom of an upwardly and rearwardly inclined fresh air flue 11, extending throughout the width of the space between the plates 1 and is provided, at its front end, with a foraminous any suitable metal andcan be'in the form of;

A grate 13 is arranged within the lower portion of the comb formed between the plates 1 and in front of the plate 2, it being understood'that this grate.

can be of any preferred. construction. For example, and as shown in the drawings, it can be made up of rotatable bars. Arranged within the frontportion of the space between the plates 1 below the level of the grate bars ustion chamber 14 7 back "of the plate 2 are additional plates 5 which cooperate with each other and rodlate 2 under I is a foraminous shield 15 which can be in theform pf an ornamental grille and back, of this grille may be arranged a damper inthe form of parallel pivoted slats 16 which can be operated by any suitable means, not shown, for the purpose of .contrplling the draft through the grille 15. A

Above the grille 15 are doors 17-which can be made with panels of fire resisting transparent ,or translucent material, such as mica,

These doors. when closed will prevent the es cape of products of combustion into, theroom in which the apparatus is installed. V g

. Extending laterally from the plates 1 are shelves 18 on which are mounted water pans or containers 19 having laterally 'extending filling boxes 20 the free ends of which have upwardly extending inletporti'ons 21. In installing the apparatus herem described a mantel 22 of masonry is erected about that portion formed of metal, the side walls being spaced from the plates 1 so asto.

provide fresh air compartments 23. These fresh air compartments open upwardly into the spaces between the fines 3 and rearwardly back of the containers 19 and shelves 18 and" into thespace above the Hues 3 communieating with the fresh air flue 11. This space has been indicated at-24 in Figure 3. The mantel is erected around the flues 6 and-7 where they are ex tended-rearwardly at their lower ends and the chimney is built around the outletends of the flues 3 so thatf the proda grating 26 and under this grating there may be arranged a damper 27 in the form of parallel slats. plvotally mounted. This damper can be-operated by any suitable mechanism.

not shown. Another damper 28 is arranged in the outlet end of each-flue 3 and the damp- I er 28 is secured to a transverse rod 29 having a crank arm 30. An operating rod 31 is extended from the crank arm through the front portion of the mantel and obviously by manipulating this rod the damper 28 can be I shifted to'control the flow ofthe products of combustion into the chim ey.

e arra nged above A deflecting plate 32 can '3 and extend the upper ends of the flues partly under the grating 26 for the purpose heat from the fines toward the" of deflecting grating as indicated by arrows in Figure 3.

If the heating apparatus is to be used for heating one room only opening 345' so as to close. it. The back ends of the fiues 6 and 7 will be ex .os ed'through the wall so that by opening t eda'mpers 39- fresh air can be brought into the apparatus from outside.

This fresh air'will be heated within the apparatusfand flow upwardly into the room flowing throug'hthe room the heated fresh air will escape through the grille 15, upwardly through the combustion chamber and out the chimney. Thus the room will be kept supplied with fresh warmed air. When desired the dampers 39 can-be closed to shut off the supply of fresh air.

Obviously with the device constructed as described a room can be kept supplied with 1" fresh air either .warmed or cool and as this air is delivered upwardly through the grating 26 there-will be no draft in the-room. Furthermore'the vitiated air will be carried off through'the grille 15, thusleaving the air Within the'room pure and of the desired temper'ature' Should it be desired to heat a room located back of the mantel the lower back ends of the fiues'6 and 7 would be provided with agrille 33 located in the next adjoining room through the front of the mantel it will be installed in an outside wall of thegroo'm and the chimney willbe built up from the ground outside of the wall and over the l form the necessary air chambers. various modlfications lnthe arrangement ofand into which air can flowjso as to enter the 34 can be provided in the wall of therobm aorossan opening 34 communicating with the heating apparatus and 7" back of this grille there may .be provided a damper 35 made up of parallel slats pivotally mounted and adapted to be operated by any suit-able mechanismprovided for that purpose. Furthermore, if'desired, a small manel 36 can be erected in the said adjoining room and this mantel may haye air outlet gratings 37 communicating through openings 38 with the space within the heating appa rat-us. Dampers 39 are located in the lower portions of the lines 6 and 7 and have crank arms 40 connected by a cross strip 41. This cross strip has a rod 42 extending therefrom 22 and by actuating said rod the dampers 39 can be simultaneously opened or closed. When the dampers 139 are open air will enter the fiues 6 and 7 from the adj'oining room and flow into the fresh air spaces within the heating apparatus. Thereafter heat can escape through the grille 34: and the grating 37 or,

by closing the damper 35 the air can escape solely through the grating 37.

Other roomscan be heated by providing flues for cold air extgnding from the lower portions of said room into the bottoms'of the air compartments 23. Two'of these flues have been shown at 43. Where such flues are used gratings can be employed-in the partitions between therooms close to the ceilingEM l so as to allow warm air to pass from the room in which the apparatus is located to the adjoining roonrso that it can return by way of the flue 43 to the heating apparatus. One of these wall gratings has'been indicated W at 44.- in Figure 1.

Attentionis directed to thefact that in the present structure it is not necessary to use a veneer of brick or the like upon a metal casing. Veneers have heretofore been found 1| objectionable because they soon work loose and fall. In the present instance the inantel built of solid masonry walls;and the apparatus constituting the metal portion (if the heater is installed between the walls of the mantel although cooperating therewith to Obviously the interior of the flues, etc. can be used Without departing from the present invention as claimed.
